When to Check Lubricant
It is not necessary to regularly check fluid unless you suspect there is a leak or you hear an unusual noise. A fluid loss could indicate a problem. Have it inspected and repaired.
How to Check Lubricant

To get an accurate reading, the vehicle should be on a level surface.

Use care not to overtighten the plug.
